1 DISPLAY CARTON A novel feature lies in the' provision of therespective bufi'er compartments by panel structures extending fromopposite side edges of the basic front panel, the buffer compartments atone side of the compartment being formed by a structure comprising asidewall panel, a partition panel, and appurtenant flaps successivelyhinged at the corresponding side edge of said first panel. However, theentire carton is formed of a one-piece blank, and the backwall panel ishinged to the other sidewall panel which is adjacent to the oppositeedge of the first panel, and the panel structures which are to comprisethe other buffer compartment are disposed along the blank beyond saidbackwall panel. Thus, in order to bring this last named panel structureto the proper position for forming the second buffer compartment, thebackwall is formed double, i.e., in two layers, by means of a partialinner backwall panel hinged to and doubled back over and preferablyglued to the primary or outer backwall panel. This brings the partitionpanel structure for the second buffer compartment at the proper side ofthe carton and also provides a reinforced structure adding to thesturdiness of the enclosure.

This invention relates to boxes or cartons made of cardboard ormaterials of similar properties, and more particularly to cartons whichare adapted to protectively contain and display articles of commerce,especially those of a frangible nature.

The general object of the invention is to provide a carton of this classwhich is of sturdy construction and at the same time economical inproduction.

In its preferred embodiments, the invention contemplates the provisionof such a carton which is of novel and improved reinforced construction,and also embodies improvements in the structure and means for securingthe parts to provide bufier compartments alongside the central pocket inwhich the article of merchandise is received.

Other objects, including the provision of a novel one-piece blank fromwhich the carton is fon'ned and the novel method of erecting the cartonfrom such blank will be apparent from the following specification whenread in connection with the accompanying drawings in which oneembodiment of the invention is illustrated by way of example.

In the drawing,

FIG. I is a plan view of a one-piece blank from which the novel cartonmay be formed;

FIG. 2 is a fragmentary view showing the two layers of the roof panelfor the article-containing pocket, folded and secured together;

FIG. 3 is a similar view showing the left-hand portion of the blankfolded over against the central area as a further step in the forming ofthe carton;

FIG. 4 is a view in perspective of the blank at a further stage, inwhich the panels and tabs comprising the pocket partitions are partiallyfolded and ready to be brought to their glued positions;

FIG. 5 is a bottom end view of the completed carton, with the closureflaps open;

FIG. 6 is a view in perspective of a completed carton in erect position,with portions broken away to reveal the interior construction of thepocket partitions;

FIG. 7 is a view in vertical section taken on line 7-7 of FIG. and

FIG. 8 is a perspective view of the completed carton.

The completed carton shown in FIG. 8 is given the designation 10, but indeveloping the disclosure the one-piece blank designated 100 in FIG. 1will be described first.

The front-wall panel 12 is flanked on both sides by the sidewall panels13 and 14. Extending from and hinged to the sidewall panel 13 are panelswhich are to provide one of the buffer compartments of the completedcarton. These include a narrow panel 15 (which will have its rearsurface adhered to an edge portion of the ultimate backwall structure aswill'be described), the partition panel 16 and a stub glue flap 17, forultimate adhesion to a portion of the front panel 12.

Hinged to the opposite sidewall panel 14 is the primary or outerbackwall panel 20 which-is of an area the full width and length of thecarton. Then comes an abbreviated panel 21 which will constitute aninner lamination of the backwall structure to be adhered to the surfaceof the panel 20. Hinged -to this inner partial panel is the otherpartition panel 22 and its glue flap 23, which will provide the secondbuffer compartment.

As suggested in FIG. 1, the fold lines between panels which willcomprise outward exposed areas of the carton are merely creased orscored lines such as shown in broken or dash lines, for example at a,but the fold lines for interior panel junctions may be of a slit orperforated and scored nature as suggested at b.

End closure flaps and tabs are provided at each end of the front andside panels and include the top and bottom closure panels 25 and 26hinged to the front panel 12 and provided with the respective flaps 27and 28. End flaps for the sidewall panels are at 29 and 30, and at 31and 32, respectively.

Hinged along the line 33 is a panel structure comprising themirror-duplicate panels 34 and 35, hingedly connected along the creaseor score line 36; and one of the first steps in erecting the carton maywell be the doubling of the panel 35 over the mating panel 34 andadhesively securing the resulting structure together to provide the roofstructure 40 for the article containing display pocket. This is clearlyshown in FIG. 2 of the drawing.

The next step will logically be the folding of the blank along thecrease or scoring designated a, so that the partial inner back panel 21overlies and is preferably adhesively secured back-to-back to the outerpanel 20, as clearly depicted in FIG. 3

Then partition panel 22 may be moved to a position substantially at aright angle to the doubled backwall structure 50, with its glue flap 23flared forwardly to ultimately be adhesively secured to the front panel12 along the area indicated at 51. This is suggested in FIG. 4, and inthat FIG, the narrow panel 51 is shown folded at a right angle to thesidewall panel 13, the partition panel 16 bent at right angles to thepanel 15, and the glue flap .17 flared outwardly to ultimately beadhered to a small area 52 at one side of the center of front panel 12.

Now the pocket and compartments may be completed by folding theright-hand structure along the score line a2 until the sidewall 13stands at a right angle to the front wall 12 and the glue flap or tab 17is adhered to the area 52 of the front panel. This establishes thebuffer compartment indicated at 60 in the right-hand portion of FIG. 5or at the left in FIG. 6. Then the opposite structure is folded at rightangles along the lines a3 and a4 and the flap or tab 23 glued to thearea 51 on the inner surface of front panel 12. Finally, the basiccarton structure is completed by the gluing of the area 53 at theextreme edge of double back panel 50 to the area 54 on the narrowconnecting panel 15. Then the pocket 61 and the bufier compartment 62are completed.

The article to be contained, represented by the bottle or vial A, maythen be inserted through the open bottom end of the carton shown in FIG.5, being guided by the sloping end edges 16' and 22 of the partitions 16and 22.

The closure flaps and tabs 25-32 are then folded and tucked in theconventional ways to close the carton. In closing the upper flap 25, theroof 40 is moved to the inclined position shown in FIGS. 68 and thelatter is retained in this position by virtue of the relationship of itsheight x with respect to the distance y from its fold line 33 to theclosure flap 25 (see FIG. 7).

Openings 71 may be formed in the front wall of the carton through whichonly a portion of the contained article may be seen; and these openingsmay be separated by a band or panel area 72 which may bear identifyinglegends or labels or other printed or pictorial promotional matter. Itwill be noted that the positioning of the viewing openings 71 and theareas 51 and 52 to which the flaps 17 and 23 are secured, are such as toavoid interference one with the other, and at the same time present asymmetrical appearance at the front of the carton.

Incidentally, it may be mentioned that the adhesive for securing alljoints, 235l, l752, 20--2l, 2l, may be applied in streak or stream formto areas 15, 23, 17, 35 and 56 (both sides of2l lclaim:
